Default How do I remove differential cross shaft bolt?

I've done this before, but seem to have forgotten how?

I have the rear cover off and the bolt loose but I can't get it out. I slide it as far as I can and it hits the bearing cap. I don't remember removing the bearing cap to install the locker, and I had to remove the cross shaft to install the locker. What am I doing wrong? I've already tried turning the wheels but it seems like no matter where the bolt ends up, I can't get it past the bearing cap?

You don't need to completely remove the bolt. You just need to get it out of the way far enouogh to remove the shaft. Do you have enough room to do that?

I pulled the bolt out as far as I could and then pushed the wheel towards the outside of the car and the shaft moved about 3/4" out but then it seemed like it snagged on something and I couldn't push it out with my finger. Maybe I have to pry on the part of the locker that is next to the shaft? Hmm, now that I think of it, maybe that would work.

Doesn't sound good, Enrique. I've broken those cross shaft retainer bolts before. One, I was lucky enough to fish out the broken piece, and get the shaft out. The other, no such luck, so I left it alone in there. Then one day, I'm driving down the freeway, and get this BAM BAM BAM under the car, whole car shaking violently. It was the cross shaft finally working itself free, and whacking the pinion gear as the diff spun around. Scratch one 10 bolt rear.

I don't think mine is broken. I think I'm just not doing this right. I'll report back in a little bit.

I have to get these axles out, I haven't driven the car in so long...

okay, I got the shaft out. It had some pretty deep "scratches" on one end that I think were snagging. I think I have a spare cross shaft around here, but does anyone make a replacement (8.2 10bolt)? The instructions from Richmond for the locker mentioned replacement pins but the ones I've found online say "only for Richmond mini-spools".

Is this a Lock Right? There are a few cross shafts available for this rear end. You need to know the diameter and length.

I couldn't find my calipers but it looks like 4.75" long and 11/16" in diameter, maybe 3/4"? This is with a regular ruler.

Quick way to tell the diameter is use the open end of a wrench.

If it is a fractional size say a 3/4", then a 3/4 wrench will fit between the flats of the wrench with very little room, a 11/16 will not fit and a 13/16 will be too loose.

If the shaft wasn't loose in its bores I would recommend taking some emery cloth and clean up those scratches and reuse the shaft you have. They aren't particularly delicate. Should be good for one more round.

I don't know, I guess scratches isn't the right word. They're more than deep enough to catch a nail on and emery cloth won't polish them out. That and the powertrax instructions state in bold letters to replace it if ANY scratches or imperfections are present?

Also it looks like it is a 3/4" diameter. The shaft also has to flat sections that the fit perfection into the 11/16" wrench.
